I've read 38/50. A grand effort but there are still some rather obvious holes.

Surprises for this list- Enid Blyton with a top 10 finish. She has always been popular in Australia, but she hasn't had any recency effects like a movie to boost the profile of the Magic Faraway Tree. And I'm very surprised to see Dr Seuss only emerge in the last 5.

As always there are a few books I've never heard of - Stew a Cockatoo and The Flying Orchestra.

I'd include Where is the Green Sheep too. I think I like it better than Possum Magic! Although that's a classic in its own right of course. I'd include The Gruffalo I think it's a shame it's not there. And I think it's a crying shame that Patrick Ness was omitted. And I think I'd swap The Hunger Games for Twilight.
